A series of weapons based on the Apocrean ability to steal souls.
Sword = "Power"
Normal hits = like a faster, larger brandish that does zero damage but knocks many souls out of enemies.
Charge = destroy all of the souls you've collected, dealing heavy damage to all enemies that have had their soul taken. As a side effect, the sword deals an area of effect around it that deals damage based on the number of souls stolen. If very few souls are stolen, this side effect is almost meaningless.
Gun = "Vision"
